AmethermModel MS35 Series - Inrush Current Limiters for High-Power Applications

SHARE
The MS35 Series of inrush current limiters by Ametherm are designed to handle up to 800 Joules of energy and support steady-state currents ranging from 10 A to 50 A. Built to withstand the rigors of demanding high-power applications, these power thermistors are instrumental in alternative and green energy systems. They help prevent current spikes in power generated from wind turbines, solar panels, and other renewable sources as it is fed into batteries, inverters, and other energy storage systems. In addition, MS35 inrush current limiters regulate the release of battery energy in electric vehicles and play a crucial role in pre-charge circuits for various types of battery chargers. These components are essential for maintaining system reliability and efficiency across multiple high-power applications.
